NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern:

Be it known that we, FRANK L. DYER, a citizen of the United States, and a resident of Montclair, in the county of Essex and State of New Jersey, and DELOS HOLDEN, a citizen of the United States, and a resident of Upper Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Appa! Moving-Picture Films, of

Our invention relates to apparatus for the production of amoving picture film characterized by the arrangement of the photographs in two arithmetical series the members of which alternate, and one series being shifted longitudinally, of the film 'as rea'rds the other series, so that the pictures ofnot follow each other on the film in regular numerical sequence but the photographs of one series are preceded by photographs of the other series which are representative of later phases of movement, wherebyit becomes possible to exhibit the pictures of the two series in proper numerical order at separate display openings which are situated at some distance .from each other, by intermittently moving the film at each opening in alternation a distance equal to the length of two adjacent pictures.

he pictures of one series are all exhibited at one opening and the pictures of the other series at the other opening and there may be a'continuous or uninterrupted exhibition of stationary photographs somewhat analogous tothe exhibition of dissolving views and flickering entirely eliminated.

' shutters The present invention has for its object the provision of means whereby such positive moving picture films may be printed directly by the simple passage of the film through the apparatus from negatives having the usual arrangement of photographs in a continuous unbroken sequence.

In order that the invention may be better understood, attention is directed to'the acco anying drawings forming part of this specification, and in which Figure 1 is a vertical sectional view of an apparatus constructed in accordance with front views showing respectively the upper and lower and exposure openings of Fig. 1;

Fig. 4 is a diagrammatic view showing the Specification of Letters Patent. 1 Application filed December 21, 1905. Serial No. 292,833.

In all the views corresponding parts are designated by the same characters of refer ence.

printing machine will be situated in a dark room close to, a wall 1 provided with a pair of openings 2, 2 which are closed by condensing lenses 3, 3 which receive the light from any suitable source and direct the same to the upper and lower exposure openings 4 and 5 respectively. In front of the opening 4 is a rotary shutter 6 and in front of the opening 5 is a similar shutter 7, said shutters being provided with cut-away portions as shown, of suflicient extent toenable a proper exposure to be made when continuously rotated in any suitable manner, as is well understood. The two shutters are shown as set with the cut-away portions 180 degrees apart, but thisis immaterial, as the shutters may be set in any positions whatever so long'as the cut-away portions cross the openings 4 and 5 during the periods of rest of the films at such openings.

cidently or in alteration atthe two openings, but in the machine illustrated the said periods occur in, alternation. The exposure openings 4 and 5 are formed in fixed plates 8 and 9 respectively. The sensitive and negative films a and b respectively pass directly hind the said openings, being suitably held by plates 10 and 11 which may be hinged along one edge if desired to permit the films to be readily tlneaded through the apparatus. The sensitive film passes from a suitable supply reel over a conit is held in engagement by an idler 13 and '14,'thence between the plates 8 and 10, and then over the idlers l5 and 16 to form a loop 05. This film then passes over an idler 17 thence between the plates 9 and 11 and over the idler 18 to form a loop 6. It then passes over a continuously .operated sprocket 19 with which it is held in engagement-by the idler 20; thence over an idler 21 tofa" suitable take-up reel. The negative film 7 These periods of rest may occur either coin-- tinuously operated sprocket 12 with which Patented Sept. '20, 19 10.

forms a loop a, passing thence over an idler passes from its supply reel over the continuously operated sprocket 22 w1th whlch it is held in engagement by the idler 23 and forms a loop f. It then passes over the idler 24 and between the plates 8 and 10 thence over an idler 25 to form a loop 9 which is, of different length from the loop (Z, being either larger or smaller. The film b then passes over'the idler 26 and between the plates over an idler 27 to form a loop 71; thence over the continuously operated sprocket 28 with which it is held in engagement by an idler 29; thence over an idler 30 to a suitable take-up reel.

The film feeding mechanism comprises means for intermittently feeding the films at two exposure openings 4 and 5 and may be of any suitable type. that shown being illustrated in U. S. Patent No. 714,845

granted December 2, 1902 to James H. Vhite, and comprises the two oscillating frames 41 and 42 having teeth 33 which pass through slots in the plates 10 and 11 respectively and engage the usual holes or perforations 2' provided along the edges of the films a and b. one end of each of said frames being pivoted at 34 to a link 35 which is pivotally supported at 36 by an oscillating arm 36 and the other end of said frames 41 and 42 being pivoted at 37 to a crank 38 carried by a shaft 39, driven through the gears 31 and 32 by any suitable driving mechanism. The intermittent movement of the teeth 33 will carry the film at each engagement a distance equal to twice the height of the openings 4 and and the films will be so threaded through the apparatus that differentsections will be brought to rest and exposed at the openings 4 and 5, those which are brought to rest at the opening 4 being moved past the opening 5 without stopping, by the feed mechanism located at said opening, and viceversa those sections which are to be exposed at the opening 5 will be carried past the opening 4 without any exposure, so that the impressions produced by thelight admitted by the shutters 6 and 7 respectively will fall upon distinct portions of the film a, said portions alternating with each other. Thus as shown in Fig. 4, the ninth picture of the negative is brought to rest at the lower exposure opening opposite a blank section of the film a, situated between sections upon which the second and fourth pictures of the negative have already been printed at the upper exposure opening. In this diagram, all the photographs of the negative which correspond to even numbers are printed at the upper ex osure opening and all the photographs 0 the negative corresponding to odd numbers are printed at the lower exposure opening. The loop g of the negative film 'b is smaller than the loop (I of the sensitive 9 and 11 from which it'passes film (1, thus producing a longitudinal'shifting of one film with respect to the other between the upper and lower openings. It will be obvious that in case the intermittent feeding devices at the two openings 4 and 5 move simultaneously in the same direction the loop may be dispensed with but the film a will still be provided with a loop (Z so that the relative shifting of the two series of pictures will be obtained.

Fig. 5 shows the negative I) of the usual type. the objects photographed being-shown as a bird flying toward the left over a steeple and the photographs occur in a continuous, straight line, numerical sequence, Fig. 6 shows the positive which will be obtained from the said negative wherein the pictures are arranged in two arithmetical series the members of which alternate and in which one series is shifted so that its pictures are preceded by pictures of the other series which are representative of later phases of motion, as is clearly shown by the different. positions of the bird.

The operation of the apparatus is as follows: The films a and b are threaded through the apparatus in a manner shown in Fig. 4 so that the odd numbered pictures of the nega tive will be printed at the lower exposure opening and the even numbered pictures at the upper exposure opening. The two films arernoved together by the teeth 33 alternately at each opening a distance equal to twice the height of the said openings, the periods of rest occurring during the interval when the cut-away portions of the shut-. ters 6 and 7 permit the light to fall upon said openings, and the result is that the impressions received upon the film a at the opening 4 will be separated by blank spaces. which spaces will be filled in at the opening 5 and by reason of the loop g being of different size from the loop (Z, the pictures of one series, that is, those printed at one open ing, will be preceded by pictures printed at the other opening which are representative of later phases of movement. 7
